Product Name: Amino-modified silane adhesion promoter     AC-21

 Appearance: Light yellow liquid 

Product Characteristics: A reactive adhesion promoter that enhances the adhesion of coatings to difficult-to-bond substrates. Also suitable for adhesives, elastomers, inks, etc., to provide excellent adhesion. When used as an adhesion promoter, it is recommended to use it simultaneously with epoxy resin coatings, silicone resin coatings, and alkyd resin coatings to improve the adhesion of coatings to glass, metals (aluminum, steel, zinc, copper, etc.), and plastics (EVA, PET, PP, PE, PVC, etc.). (1) As a bonding promoter to improve the adhesion of polymer coatings or adhesives to glass, metals, or other polymer surfaces 

 (2) Enhances the bonding strength of epoxy resins 

 (3) Improves water resistance and salt spray resistance Applications: Epoxy resin coatings, alkyd resin coatings, silicone resin coatings, acrylic resins, polyurethane resins, etc. This product can be directly added to various resin coatings or used as a primer on difficult-to-bond materials. 

 Recommended Dosage: 

 ? Epoxy resin coatings: 1-4% of the epoxy resin coating and curing agent; 

 ? Silicone resin: First dilute AC-21, then add it to the system at a ratio of 1:1 = diluted solution: coating; 

? Alkyd powder coatings: Add 1-2%, 

? Resin modifier: Recommended dosage 0.5-1%, mix before use. 

 Note: This product contains flammable solvents. Keep away from fire sources and store in a cool, ventilated place. It is irritating to the eyes and skin. If it comes into contact with the skin, rinse immediately with plenty of water. Due to the presence of active amino groups, the color may darken over time, but this does not affect performance.
